Abstract: To form a high-quality image regardless of a printing rate.SOLUTION: In an image forming apparatus 1, when the average printing rate is relatively low, a little amount of toner is consumed from the inside of a toner storage unit 41, and in a stage in which a large amount of toner with a high degree of deterioration remains, a new toner is supplied little by little by a relatively small amount. The image forming apparatus 1 can thus reduce the degree at which the characteristics of toner changes and prevent the occurrence of density unevenness during the formation of a toner image. When the average printing rate is relatively high, the image forming apparatus 1 consumes a large amount of toner from the inside of the toner storage unit 41, and in a state in which a little amount of toner with a low degree of deterioration remains, supplies a relatively large amount of new toner. The image forming apparatus 1 can thus maintain the substantially constant characteristics of toner, reduce the number of times of supply of toner, and reduce the required time and reduce the consumption of toner.SELECTED DRAWING: Figure 9
